[The campus includes the Olympic Stadium, about 40 faculties and institutes, the Cultural Center, an ecological reserve, the Central Library, and a few museums.] Del Moral had an intermittent partnership with Mario Pani, whose strong personality and commitment to a modified version of the International Style led del Moral to pursue a different approach. The principal works carried out in collaboration with Pani were preparing the outstanding and exemplary master-plan for the Ciudad Universitaria (plan completed 1952) and the Rectoria (1951-1952) in the Ciudad Universitaria (with mural decoration by David Alfaro Siqueiros).
